So far, I have been able to hold 8 web sites (New Page button is out at this point), listen to Pandora, browse the app store, play Real Racing back and forth, use BeejiveIM, all at the same time on the iPhone 4 without having any of those unloaded and the phone still runs smooth so far. Only a couple of hiccups occasionally. Edit: just to clarify, hiccups are brief freezes when switching to another page in Safari. Other apps work fine and smoothly. What's your story?
